Frank Shaw drew Nestor aside as the boys searched about the cavern for nuggets. As a small one was occasionally discovered, the quest was conducted with an enthusiasm which left the two to themselves.
"It is a strange chance that has brought us to this mine," Nestor said, thoughtfully. "It seems like a fairy tale come true.""Do you really think this is the long lost Tolford mine?" asked Frank.
"I think it is," was the reply. "The location is right, at least.""It is remarkable," Frank said, "but we can talk of that at another time. I called you over here to ask you more about the fourth man--the one you referred to, but a short time ago, as having visited the Cameron suite that night. I didn't think much of the idea when you suggested it, but, somehow, I can't get it out of my head. Do you still believe there was a fourth man? If so, what was he there for?""That will show in time," replied Nestor, with a little pause after each word.
"But," insisted Frank, seeking to argue the matter in order to bring out the opinion of his chum, "these other men had strong motives in doing what was done there, and you don't indicate any motive the fourth man might have had!""I have a faint hint of a motive humming in my brain," Nestor answered, "but it is not sufficiently well developed to talk about now. There was something afoot in the building that night that has not yet come to the surface.""You surely don't believe the tales told by Scoby and Felix, or by Don Miguel, either?" asked Frank.
"They may be telling the truth, or part of the truth. However, Scoby and Felix are not sincere in their statements. There is something they are not telling.""Well," Frank observed, "we ought to be getting down to brass tacks.
If we get Fremont away from those ruffians to-night he'll want to be jumping at something right away, and there ought to be a line of work laid out.""Don't get excited," laughed Nestor. "We're getting along pretty well.
We've found the mine, and we've taken three prisoners. If there was a fourth man in the mixup that night, we'll soon know who he was and why he was there.""I wish I knew whether the munitions of war got across the border,"Frank said, after a pause.
"The mountain has been remarkably quiet to-day," suggested Nestor.
"What does that mean?"
"Don't you think the men would be ****** a lot of noise if they had arms in their hands?" Nestor asked.
"Perhaps they are ****** noise somewhere."
"They may make all the noise they want to, if they keep off Texas soil,"replied Nestor.
"I have been talking with Stevens," Frank went on, "and he gives a doleful account of the situation in New York. They left nearly two days after you did, you remember. It is said that Cameron is not likely to recover, and that he still, in a rambling way, talks of Fremont as the person who assaulted him. That looks bad.""It is fortunate that we got the boy out of New York," replied Nestor.
"Even the temporary captivity he is undergoing is better than the Tombs.""I'm afraid he's on the way to the Tombs now," Frank said. "He surely is unless we can do something immediately. The big rascal may come upon a band of outlaws any minute that would be too strong for us to attack."During this talk Jimmie had been searching for nuggets on the eastern side of the chamber, finding a small one occasionally when the light was turned toward him. As Shaw finished speaking the boy found another, and the watcher was wondering how rich the earth was.
Then he saw the boy, stooping to the floor of the cavern, evidently in quest of more gold, he being at that time close to the east wall, suddenly throw up his arms and disappear, apparently through the very floor of the chamber.
Frank stood for a second looking toward the place where this strange disappearance had taken place, rubbed his eyes to make sure that he was wide awake, and then uttered a cry which brought the others hastily to his side.
When the boys reached the point of disappearance they looked for a fissure in the rocky floor, but found none. Instead, they saw a round, smooth opening into what seemed to be another tunnel. The light, when held into the dark break in the rock, revealed a landing about six feet down, but Jimmie was not in sight. Presently, however, the alarmed boys heard his voice, coming up out of the darkness.
"Hey, there!" he said. "Get a rope and a light! I'm on a toboggan!""In a second," Harry replied. "Are you falling?""No, I'm hangin' on with me toes!" was the reply. "Hurry up, you fellers! I'll drop clear into the middle of the world if I let go!"Harry darted away to the outer chamber and brought a line from his camping outfit. Tying a piece of stone to one end, to act as a sinker, he dropped it into the mouth of the tunnel.
"Catch it!" he called to the boy.
"Nothin' doin'!" returned Jimmie. "I'm hangin' out in space. If Ishould let go with one finger or one toe I'd take a tumble through to China. One of you fellows come down on the rope. Hurry!""Are you hurt?" asked Nestor, anxiously.
"Not on your life, only in me feelings," replied Jimmie. "It breaks me tender heart to get into a hole I can't help meself out of! Come on down with that rope!"Nestor drew up the line, tied one end about his waist, and, wondering what might lie within the forbidding place, and where it might lead to, was slowly lowered into the tunnel. The flashlight showed a level space about two yards in extent at the bottom of the shaft, directly under the opening, but beyond that the tunnel dropped away toward the east and the middle of the Chinese empire, as Jimmie declared. The fall of the passage, which was not more than six feet in diameter, was at least fifty degrees.
As soon as his feet struck the little landing Nestor saw Jimmie lying flat on his stomach on the incline below, hanging on with his fingers for dear life. As Nestor looked the boy's fingers slipped on the smooth rock and he started, feet foremost, down the dark passage.
